In many contexts it is useful to consider paths parametrized by the repetition of some parabolic cycles (corresponding to some Dehn twist). The matrix of the path is then a polynomial in these variables.
A possible user interface is
sage: fs1 = iet.FlipSequence(p1, ...) sage: fs2 = iet.FlipSequence(p1, ...) sage: R.<n1,n2> = PolynomialRing(QQ) sage: fs = fs1^n1 * fs2^n2
